Can I change the Sender of the DocuSign Request?
The Sender of the DocuSign Request is determined by the DocuSign User that was used to authenticate with the DocuSign API. The name and email address corresponding to the sending DocuSign user account will always be shown on/for sent envelopes. If you want to change the Sender you will need to re-authenticate as a different user each time you wish to change the Sender, or use the JWT grant to programmatically impersonate the different account users and to send on their behalf.
You can manage your DocuSign Users in your DocuSign account - here's a screenshot showing how these appear:
If you have authenticated as the first user in the list then the DocuSign requests will use that user as the sender:
If you authenticate as the second user in the list then the DocuSign requests will use that user as the sender:
If you are using v1.4 or later of fmESignature Link which use the Authorization Code Grant OAuth Flow for authenticating with DocuSign you would need to clear out the Access Token, Expires At (Host Time), Refresh Token and Account ID fields which appear on the SETUP screen each time you wish to authenticate as a different user:
Alternatively you could setup a Users table to store these values for each User and reference that table when passing the authentication credentials to the DocuSign API so you don't need to manually authenticate each time you wish to change the Sender for a request.
You can also use the OAuth JWT grant to programmatically impersonate the different account users and to send on their behalf. We are currently exploring how to implement this method with fmESignature Link to allow you to dynamically impersonate different users when sending the Request.
